Microsoft stock price peaked at 6118% of its IPO price more than 13 years after the IPO† Suppose that $15,000 invested in Microsoft at its IPO price had been worth $900,000 (6000% of the IPO price) after exactly 13 years. What interest rate, compounded annually, does this represent?

37% compounded annually

Explanation:

To find the answer we need to follow this formula:

Where:

Now we plug the amounts into the formula:

900,000 = 150,000 (1 + r)^13

900,000 / 150,000 = (1 + r)^13

60 = (1 + r)^13

Ln60 = 13 Ln(1 + r)

4.09 / 13 =  Ln(1 +r)

0.31 = Ln(1 + r)

e0.31 = Ln(1 + r)

1.37 = 1 + r

1.37 - 1 = r

0.7 = r

Thus, the annual interest rate is 37%

cognitive overload: having a lot on your mind impairs decision-making and tends to result in the simplest, but not necessarily best, option being selected.

empathy gaps: overlooking how you might feel in a different situation can result in unnecessary purchases, such as overbuying when shopping for food on an empty stomach.

optimism and overconfidence: wearing rose-tinted glasses and having unrealistic expectations about the future can affect money management and leave you unprepared for a change in circumstance.

instant gratification: seeking instant gratification drives impulsive spending and can undermine long-term planning and savings.

harmful habits: automatic or mindless behaviour can amplify a poor financial decision as it becomes a recurring event.

social norms: we are heavily influenced by the actions of others; while this can be in certain circumstances, it also contributes to the pressure to keep up with the joneses through conspicuous consumption.
